I believe (based on limited anecdotes around the net) that you can get audio out of the base station, but the remote definitely will not operate with Rockbox. I have a Griffin PowerDock, and it works just fine as an audio output (with volume dependent on the player's scroll wheel), and it also charges the device as long as I use a Rio Carbon USB-to-AC adapter instead of one of the cheaper adapters prevalent on ebay. I haven't tried connecting it to my PC to sync or transfer files yet, so I can't comment on that aspect of it.
